Definitions
- the present invention relates to a composition based on a sulfur compound, zinc and possibly a transparent oxide, its preparation process and its use as coloring pigment.
- Mineral coloring pigments are already widely used in numerous industries, particularly those of paints, plastics and ceramics.
- these pigments there are a number of compositions containing sulfur.
- products based on rare earth sulfides have already proposed by the Applicant as substitutes for pigments comprising metals known to be very high in toxicity such as, in particular, cadmium, lead, chromium and cobalt, the use of which is becoming more and more severely regulated.
- compositions based on rare earth sesquisulfides and alkaline elements have thus been described in EP-A-545746.
- sulfur-based pigments In addition to the problem of toxicity in certain cases, sulfur-based pigments generally have the drawback of releasing H 2 S in certain applications, for example during their incorporation in media containing traces of water, like polymers, and especially when this incorporation takes place at a relatively high temperature, for example at least 200 ° C.
- the coating of a support based on at least one sulfur-containing compound with a zinc compound is disclosed in DE-A-4 404 953.
- the object of the invention is to provide such improved pigments.
- the composition of the invention is characterized in that it further comprises a layer based on at minus a transparent oxide deposited on the surface of the support.
- the composition is characterized in that it further comprises fluorine atoms.
- the invention also relates to a first process for preparing a composition of the previous type, which is characterized in that the support is brought into contact, a precursor of zinc, ammonia and / or an ammonium salt and, where appropriate, a precursor of the transparent oxide and a fluorinating agent, and the zinc compound is deposited on the support and, if necessary, the transparent oxide is precipitated on said support.
- the invention further relates to a second method for preparing a composition of the previous type which is characterized in that the support is subjected to a fluorination treatment first, then, secondly, we put in contact with said support thus treated, a precursor of zinc, ammonia and / or a salt ammonium and, where appropriate, a precursor of the transparent oxide, and the zinc compound on the support and, if necessary, the transparent oxide is precipitated on said support.
- the invention also relates to a third method for preparing a composition of the previous type which is characterized in that, in a first step, the support is brought into contact, a zinc precursor, ammonia and / or a salt ammonium and, where appropriate, a precursor of the transparent oxide, and the zinc compound on the support and, if necessary, the transparent oxide is precipitated on said support then, in a second step, the fluorination treatment is carried out.
- the invention further relates to a fourth method for preparing a composition of the previous type which is characterized in that, in a first step, the support is brought into contact with a precursor of the transparent oxide and precipitated the transparent oxide on said support then, in a second step, contact is made the support thus obtained with a zinc precursor, ammonia and / or a salt of ammonium and the zinc compound is deposited on the support.
- the invention relates to the use as coloring pigment of a composition of the previous type or as obtained by one of the methods of the type described above.
- rare earth means the elements of the group consisting of yttrium and the elements of the periodic table number atomic inclusive between 57 and 71.
- the composition according to the invention firstly comprises a support, forming a core, based on at least one sulfur compound.
- This compound may in particular be any compound usable for its pigmentary qualities.
- This sulfur compound can be in especially a sulfate or a sulfide.
- a sulfide we can cite the cadmium sulfide or sulfoselenide, mercury sulfide. Can also mention the pigments of the "ultramarine" type purple 15 CI 77007 and blue 29 CI 77007 according to the Color Index classification.
- the support when looking for compositions based on non-toxic elements, is chosen from the products already described by the Applicant.
- the support can be based on a rare earth sulfide of the Ln 2 S 3 type , Ln being the rare earth, as described in EP-A-203838.
